To all whom t ma at I, HARRY H. BAER, a

Be it known t I citizen of the United States, residing at Orrt vine, inthe Vacuum Ore-Separator,

county of Wayne'and State of Ohio, have invented a new and useful of which the following is a specication.

remove by suction My invention relates to improvements in 4vacuum ore separators, in which an openk ended inclined, rotating cylinder is employed, said cylinder provided with agitating blades and vacuum creating means,

whereb air is drawn from the open end of the cy being tom or lower end of the open ended cylinder. Further the invention consists in providing an endless conveyer whereby the material designedto be treated is deposited intermediate the ends of the rotating cylinder. v

The objects of the invention are, first, to the lighter particles of metal producing ores or other metal carrying products, after the ore, rock or.v other inder, the'partial vacuumv formed metal carrying products have been reduced looking att-the y right by a grinding process toa predetermined'degree of neness; second, to feed the 'ground product upon an endless conveyerl whereby distribution is brought about by exbetter tendingthe endless conveyer into the 1nclinedrotating cylinder; and third to withdraw the air Ifrom the rotating cylinder while `it is being rotated, thefinclination of the cylinder being regulated or adjusted withreference to the material being treated.'

These objects, together with other objectsreadily `apparentto those'skilled inl the art, may, be attained-by the construction illustrated fin the accompanying drawings,

althou hv the'invention may be embodiedin other.y orms, the construction illustrated/being'chosenby way of example..` drawing.: isa side elevation. Fig; 2 .is an end view Fig. 3 isan enlarged vview showinga portion its .driving ring and the metal receiving spout and aportion` of the vacuum chamber.'

iilled by the inrush of air at the bot-v conveyer bars 9.

Figure 1 v hand endl of Fig.. 1..

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings.

The frame of the machine to which the various parts are attached is made up ofthe A tutes what might be termed the front of the vacuum chamber proper. The front or lower end of the cylinder 5 is supported by thevbearing ring v8, which ring is securely connected to the pivoted side bars 9, said side bars being pivoted to the fixed bearing ring 6 orits equivalent.

, 'Upon-the shaft 10 is mounted the sprocket wheel 11. Above the shaft 10 is located the shaft 12, which shaft is driven by the belt 13 and the pulley 14, which pulley is mounted'upon the pose of imparting movement to the' endless 15 which is extended into the cylinder 5, the shaft 16 is provided, which shaft is properly journaled in yone of the pivoted For the purpose of rotating the shaft 16, together with the different parts connected'thereto, the sprocket wheel 17 is secured upon the shaft 16. For the purpose .of imparting motion -to the shaft 16 the sprocket chain 1 8 is provided, said sprocketchain alsoimpartsjrotary' motion to the vshaft 10, the drivingwheel for the sprocket provision. must be made for holding the sprocket chain 18 in proper tension, regardthe cylinder 5 and in order to accomplish this result'the drive chain 18 is located around the sprocket wheel 19 and extended Y down and around the sprocket wheel 20,

vthence upward and over the idler 21, which idler is journaled in the bracket 22, said bracket being secured `to and adjustable with one of the pivoted bars 9, the drive chain. is

shaft 12. For the purless of the adjustment of thev lower end of located around the extended around the sprocket wheel 17, thence under the sprocket wheel 11, and upon the sprocket wheel 19.

It will be understood that-by journaling the'shaft l2 and the shaft 23 in bearings fixed to the frame proper the tension of the drive chain will not be changed by reason of the adjustment of the lower end of the cylinder up or down. It will be understood that the adjustment of the lower end of the cylinder is comparatively slight, a` few inches being sufiicient to bring about the results desired. The endless conveyer 15 is pulleys 24 and 25, the pulley 24 being the driving pulley for the endless conveyer. The endless conveyer 1s inclosed in a suitable casing 26, which casing is held at the proper angle and in substantial alinement with the rotating Cylinder 5, by means of the shaft 10 and the cross bar or bolt27. y

For the purpose .of conducting the material upon the conveyer 15 the cas1ng 26 is provided with the feed tube 28, into which feed tube is extended the funnel 29, which funnel is telescopically connected to the'feed tube 28. The funnel 29 should be held in fixed relationship with reference to the frame which may be by the bar 30 or its equivalent. Above the funnel 29 is located the feed roller 31, which feed roller is driven bythe sprocket wheel 32 and the drive chain 33, said drive chain being drivenl by a sprocket wheel mounted upon the shaft 12. Above the feed roll 31 is located the hopper 34, into which hopper the previously ground ore, rocks amount of the material fed on to the conveyer 15 being regulated by means of the adjustable gate 35, which adjustable gate may be of any desired construction, as its only Objectis to regulate the quantity to be fed upon the endless conveyer.

The cylinder 5 is provided upon its inner surface with radial agitating blades 36, which blades are formed of alength to correspond substantially with the length of the cylinder. It will'fbe understood that as thecylinder is rotated the material fed into the cylinder will be agitated, thereby mingling the material with the air as it passes through the open ended cylinder.

At the upper end of the cylinder and communicating therewith is located a separating chamber or box 37 to which is attached the .suction pipe 38, said suction pipe leading to an communicating with the suction fan 39, which suction fan is driven .by the belt 40 or its equivalent. Within the separating chamber .is located the balie plate 41, which is inclined downward and away from the cylinder Land is located between the -cylinder and the outlet end of the suction pipe 38. The baile `plate 41 is for the purpose of separating the air and directing such or other material is placed, the

from the refuse or lighter materials or nonmetal portions of the ground ore or rock material to the inclined bottom of the separating chamber or box 37.

At the lower edge of the inclined bottom is located the hinged door 42, said hinged door being automatically opened by the weight of the material or refuse coming againstvthe door. For the purpose of normally holding the door closed a suitable spring 43 may be provided, but the construction of this spring is immaterial.

It will be understood that the suction of theair against the inner surface of the door holds the same closed until the weight of the refuse overcomes the suction or overcomes the strength of the spring at which time the door is automatically opened and the refuse permitted to pass through the opening.

As above pointed out signed to be treated desired degree of the rock or ore deis first ground to the ineness, but owing to different degrees of richness and different kinds of metal bearing ores, different degrees of inclination of the separating cylinder are necessary. Owing to the fact that some metals are heavier than others it is necessary to adjust the inclination of the cylinder so that the. precious metals will not be drawn upward, but move down the inclined cylinder and be depositedin a suitable receptacle or spout 44. For the purpose of' imparting rotary motion to the cylinder 5 the ring 45 is provided, which ring is secured to the cylinder in any convenient and well known manner. Said ring is preferably L-shaped in cross section so as to provide suitable lianges, one of said flanges being for the purpose of providing means for attaching the ring to the cylinder and the other flange being for the purpose of providing a contact surface for the driving wheel 46, the driving wheel 46 being securely mounted upon the shaft 16, which shaft is driven by the sprocket chain 18 and the sprocket wheel 17. For the purpose of reducingthe friction as between the bearing ring 8 and the drivin r ring 45 anti-friction rollers 47 should be provided, which Aantifriction rollers are located so. tha-t the thrust of the driving ring will come against the anti-friction rollers 47, said anti-friction rollers being journaled upon suitable bearings 48, Which may be ordinary lug bolts.

For the purpose of adjusting the 'inclination ofthe cylinder and holding the same in proper adjustment, the screw threaded support or shaft 49 is held in suitable brackets 50. Upon the screw threaded lshaft 49 is located the adjusting wheel 51, said wheel being provided with a screw threaded opening through which the screw threaded shaft passes, by which arrangement rotating the .wheel in one diprovided, which shaft is rection will elevate the shaft androtating it in the opposite direction will permit the shaft to move down. To the top or upper end of the shaft 49 is attached the head 52 which head forms a support for the cross bar 53, `which cross bar is attached in any convenient and well known manner to the opiee of this patentmay be obtainedfor pivoted bars 9. 4 v

For the purpose of regulating the suction of the fan 39 the shutter 54 shown in dotted lines Fig. 1 is provided, which shutter is adjusted by `means of the screw threaded rod 55 and the wheel. 56.
